Confirmed on x86_64-linux with 4.1/4.2/4.3/4.4 and on i686-linux 4.0.
i686-linux 3.4.0 to 6 give a proper error so this is a regression.

Wouldn't this be a candidate for forming a superblock from hot traces of
a function? Thus in the testcase

I agree that we need to document this change. And I agree that the new
behavior
is more reasonable.
Can we add this example to changes.html? It looks different enough than
the existing one.

Note that C++ objects need not be larger than 8 bytes to qualify for returning
on the stack (and thus subject to this cleanup problem). Any class with a copy
constructor, for example, seems to be affected.
